Output voltage ripple
Assuming a resistive load, the output voltage ripple is directly tied to the output current
ripple.
In a single ended architecture, the output current is the current flowing on the inductor when
it re-circulates through the rectifiers. Referring to
mode on page
In IL-4 architecture, output current is the sum of the 4 current flowing on each inductor. Even
if the current on each branch is the same as in the single ended architecture, the T
between the driving signals implies that output current has tiny ripple. Following figure
shows both the current on each branch and the final I
Figure 11. Step-up current waveforms for Interleaved 4 architecture
Respect to single ended architecture, input and output current ripple are reduced a lot due
both to the split of the incoming current in the 4 branches and the related shift.
9, higher is the inductance of the inductor, smaller is the current ripple (I
